This module will look at step ten. It is essential to ensure that provision is made to allow for make-up or replacement air to replace the smoke mass being vented by either natural or mechanical means. The inlet air may be provided by automatic vents, doors or extract points in other reservoirs. These inlets must be located below the anticipated smoke layer depth and if usually closed, they must open on receipt of the same signal that operates the rest of the smoke ventilation system.
